Gardeners' Notes:

I have not fuzzed much with this plant, and yet it has formed wonderful clumps in areas of my garden. Having said that, I did go thru the trouble in 2012 to collect and sow seeds and did not see much germination going on. Overall, very easy and lovely plant.

Some authorities claim this species is hardy into zone 7...if you are in that zone and want to try it, then I'd suggest mulching it well over the winter.

I have been growing this plant in my Zone 7 garden for more than 5 years with no special protection in the winter.

This is undoubtedly the most popular of the Habranthus species and is native to Brazil. Like most of the South American rain lilies, it tends to have higher moisture requirements than other rain lily species. In my garden, its a very heavy bloomer of large pale pink flowers with green eyes in starting late May. Its also a rapid multiplier, quickly forming thick clumps from both offsets and seeds. Recommended for growing in zones 8-10.

This is among my favorite of all rain lilies because of its size and that it continuously blooms in waves from April through about September (on the gulf coastal plain). The large Hippeastrum-like flowers all face in the same direction and give a charming effect. They are about 4" long and across and on stems from 12" to 24", depending on how much rain has spurred them to bloom and whether they are in shade or sun (shorter in sun). The leaves are about 1/3" wide and are flat and floppy but not unattractive in the garden.

The seed should be collected as the pods are just showing yellow and beginning to split (the seed will be very black and very shiny) and sown immediately (not allowed to dry out). They germinate immediately when sown in this manner. If allowed to dry out, they will germinate, but much later, sometimes as long as a year. They produce copious seed and are easy to naturalize.

Like the Hippeastrums, Habranthus is hardy where ever the ground does not freeze and summers are hot. I've seen magnificent swaths of the stuff at the top of Z 8 and if mulched, they could probably handle much colder. They are also excellent and forgiving pot plants but should be left outside during summer so the rains can touch them.

Great little bulbs that come up and bloom when least expected. A nice summer rain and you will be blessed with pink blooms about 8" to 10" tall all over your yard/garden. Green strap leaf foilage.
