General Instructions

  • The range of lush tropical bulbs available to you is mind-boggling ("to die for" as some Northerners would say!). But hardy spring-flowering bulbs such as tulips are a fish out of the water, in your neck of the woods. Still, if you crave seeing tulips in spring, check out your local garden retailer or florist for pots of nursery-grown tulips and other traditional spring bloomers.

Oxalis tetraphylla 'Iron Cross', Good Luck Plant 'Iron Cross', Iron Cross Oxalis, Red flowers, Foliage Plant

Oxalis tetraphylla ‘Iron Cross’ (Good Luck Plant)

Exceptionally rewarding, Oxalis tetraphylla ‘Iron Cross’ (Good Luck Plant) is a bulbous perennial forming a lush mound of rich green leaves composed of 4 heart-shaped leaflets, each with a dark purplish blotch at its base.

From early summer until frost, the handsome foliage is topped by sprays of trumpet-shaped, bright pink flowers. Easy to grow and not invasive, this Good Luck Plant makes a colorful addition to rock gardens and offers a long season of interest when grown in containers.

Oxalis triangularis subsp. papilionacea (Purple Shamrock)

Great as a ground cover in mild winter areas.

Special Note
The group of bulbs below are from warmer climates that do not require much if any cooling. Hippeastrum (amaryllis) — which thrive in hot, humid climates — make perfect 'tulips for the south' with their sturdy stems and large velvety flowers in a broad range of colors (including stripes!). In general, in areas where the garden isn't far above sea level, raised beds can improve drainage after hot, humid, summer storms.

While every effort has been made to describe these plants accurately, please keep in mind that height, bloom time, and color may differ in various climates. The description of these plants has been written based on numerous outside resources.
