Z. citrina grows well in my zone 7b garden. I love the bright yellow blooms. It self sows and is low maintenance.

I planted a dozen bulbs a few years back and hoped to have a significant patch by now. It is planted in partial sun, perhaps that is why it hasn't thrived as I had expected and as compared to other rain lilies I grow. Pretty and showy.

UPDATE August 2017: it has taken 5 years to achieve a clump look, and worth the wait as glorious! Prolific seed producer but must be container grown and then transplanted. Have not been successful with direct sowing.

Bit of a weed but a pretty weed! Not for the anal retentive gardener as it
plants itself where it likes!

Rain Lily (Zephyranthes citrina) is an introduced (naturalized) plant in Florida, Hawaii, Mississippi and Puerto Rico. It is very easy to grow and it has bloomed even when it has not rained. The color of the blooms make them very noticeable. There are many seeds in the pods so I am able to plant them in other areas. I have found that it does best in full sun; however, I have planted them in an area that receives morning sun and afternoon shade. Zephyranthes citrina forms a colony quite quickly in full sun on its own.

In this zone, Zephyranthes citrina begins blooming in June, following rains. The dainty flowers are followed by three chambered seed pods, which open to reveal black seeds. It reseeds nicely, and may bloom from seed the first year. Although they are said to be fragrant, I have never noticed.

Received some bulbs of this variety about 5 weeks ago, and they have just started blooming. A very bright color...wonderful blooms! (See posted image).

Z. Citrina is very prolific, but tends to bloom late in the zeph season. It is the parent of many fine hybirds. Its intense yellow color does not fade! as many others do. It is easy from seed if seed is sown immediately after maturing. Will often bloom the next year after sowing if given lots of TLC. No fragrance, very self fertile.


On Aug 22, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote:

The yellow flowers of Z. citrina are like most rain lilies, blooming after rain showers, especially in the fall. It is more cold-hardy than some of the other Zephyranthes species and tolerates a wide range of soil conditions, from boggy to drought. For best results, water and fertilize regularly.

It is sometimes sold as Z. sulphurea.
