This listing delivers six sets, each containing two plants bundled together, for a total of twelve individual bareroot starts. At 5 to 7 inches tall, with consistent foliage density reported across multiple verified purchases, this pack gives you enough material to fill a 15-foot border or six large containers. Customers in Texas and other hot-summer regions confirm these survive two winters and triple their flower count by the second year.

The bareroot structure here is thicker than many competing listings — roots arrive moist and snuggly packed, with visible white root tips that shorten transplant shock. One reviewer noted that each cell contained two cuttings, which they separated into twelve viable plants that were thriving after just one week. Survival rate runs high if you soak the roots for 15 minutes before planting and keep the soil consistently damp for the first two weeks. The supplier response to dead-on-arrival claims has been mixed, with some refund requests requiring a return of dead plants, so inspect root condition immediately upon arrival and take photos.

This is a fertile, non-sterile variety, meaning it will produce seeds and can spread in warmer climates. That’s an asset if you want to divide clumps and expand your garden yearly. It becomes a liability in small spaces where aggressive self-seeding is unwelcome. For the price-per-plant ratio, this is the densest coverage you can get without waiting for a full growing season.

The white-flowering variant of Ruellia brittoniana offers a cleaner, cooler visual than the standard purple, making it a strong choice for moon gardens, white-themed borders, or pathways where you want contrast against dark foliage. Florida Foliage ships these in tiny 1-inch pots with well-moistened soil, and the packaging consistently arrives intact. The upright growth habit reaches 3–4 feet at maturity, with willowy leaves that maintain structure even in heavy rain.

The biggest catch with this listing is the size-to-price ratio. Multiple verified buyers reported receiving what they described as “three little stalks” or “tiny starters” far smaller than the product photos suggest. The plants are healthy and rootbound in the pot, but they take 4–6 weeks to size up to what you’d expect from a garden-center quart pot. If you’re looking for instant visual impact, this isn’t it. If you’re patient and want the sterile white form that won’t seed about, the genetic material is sound. Feed with a balanced 10-10-10 liquid fertilizer every two weeks during the first month to accelerate the growth curve.

Sunlight requirements are listed as full sun, but partial afternoon shade in zone 9+ will produce the same bloom count with less leaf burn. The white flowers open fresh each morning and attract swallowtail butterflies reliably. One note: this is not a trailing variety — it grows upright and clumps, so use it as a mid-border or back-border plant, not for hanging baskets.

UIOTER’s offering lands squarely in the middle of the pack — two plants at 6–8 inches tall for a moderate cost. The Ruellia simplex species is the straight species, not a hybrid or sterile cultivar, so you’re getting the classic aggressive grower that reaches full size faster than sterile varieties. Verified buyers report healthy root systems and vigorous top growth within two weeks of potting. One reviewer received a bonus third plant, an unexpected value add that sweetens the deal.

The downside is consistency. Some shipments arrived as what one customer called “barely alive, spindly pathetic plants” that required immediate intervention to survive. The lack of printed care instructions is a recurring complaint — no pamphlet, no QR code, nothing beyond what the product description says. If you’re a beginner who needs guidance on bareroot soaking depth, hardening-off schedule, or watering frequency, you’ll have to look elsewhere. The soil type listed is sandy, but these will grow in clay or loam as long as drainage isn’t standing water for more than 24 hours.

Given the mixed feedback, treat this as a budget-friendly gamble. If you get a healthy batch, the plants grow fast and bloom from late spring through early fall. If you get weak stock, the window for a refund is narrow. Pair this with a backup seed pack to hedge your bets.

Florida Plants Nursery’s ‘Purple Showers’ is the most thoughtfully curated item in this roundup. The cultivar is intentionally sterile, which means no invasive seedlings, no rogue spread, and all energy focused into deep violet trumpet blooms from spring until frost. The plants ship bareroot at 5–9 inches tall and come with a soak-and-plant care sheet. Verified buyers consistently praise the root moisture upon arrival — one user noted the soil was still damp and the leaves showed no shipping stress despite traveling cross-country.

The height claim of 3–4 feet at maturity is accurate for this cultivar, with the willow-like foliage providing vertical structure that dwarf Ruellia varieties lack. The heat tolerance is remarkable; it thrives in soggy rain garden conditions and, once established, handles multi-week drought without dropping leaves. This is the best option for anyone who wants the Mexican petunia look without the annual battle against self-seeding. The only pushback from buyers is the starter size — a few received plants closer to 3 inches than 5 inches, and the thin stems look fragile. But those same buyers reported rapid growth once planted in ground with consistent moisture. Give these a 3-foot spacing because the mature width fills aggressively.

For pollinator value, the deep purple trumpets are a magnet for swallowtail butterflies and hummingbirds. The deer resistance is genuine — the upright stems and slightly hairy foliage are unpalatable to browsing animals. Zone 8–11 is the safe perennial range; north of that, treat as an annual or overwinter in a garage.

Mountain Valley Seed Company’s Easy Wave mix offers 50 pelleted seeds in a single pack, with the Red Velour color option producing deep crimson blooms on trailing stems that reach 24–36 inches. This is a true annual Petunia, not a Ruellia, so it offers the classic petunia flower form with the spreading habit that works beautifully in hanging baskets and window boxes. The pelleted coating makes these tiny seeds manageable — you can place them individually on seed-starting mix without the tweezers-and-toothpick ordeal.

The germination data from buyers is honest: around 50–80% sprout, depending on your setup. Customers using humidity domes, heat mats, and 16-hour grow lights reported 8 out of 10 success. Those who direct-sowed or used cooler windowsill conditions saw closer to half. The seeds are tiny inside the coating, so the “50 seeds” count produces roughly 25–40 viable seedlings in optimal conditions. The plants grow large quickly — one experienced grower noted that 3–4 plants per 12-inch basket is plenty, despite the pack suggesting more. Overcrowding leads to leggy competition.

The two biggest complaints are seed count disappointment and late-season germination failure. Some 2024 packs had zero germination, likely from storage temperature damage during transit. If you’re willing to start indoors with controlled heat and light, this is the cheapest way to fill multiple baskets. If you want guaranteed instant plants, skip seeds and buy bareroot starts. This pack also includes multiple color varieties if you select the mix option, giving you a rainbow effect from a single sowing.
