Title: Can a Texas Mountain Laurel be grown in Drake CO
Answered by: Barbara Medford
We don't know if we can help, but we can tell you the things we know about Sophora secundiflora (Texas mountain-laurel). To begin with it is hardy from USDA Hardiness Zones 7b to 10b; Drake, depending on exactly where it is in Larimer County, ranges from Zones 3b to 4b, with minimum annual average temperatures of -40 to -20 deg. F. As for planting it in containers, it is always worth a try, but it does have a very long taproot, and resists transplanting. Its native distribution is South and Central Texas to southern New Mexico and south to San Luis Potosi in Mexico. It grows in brushy slopes and open plains. This USDA Plant Profile on the Mountain Laurel does not show it as growing in Colorado, at all.
You may have to accept that the "mountain" in the common name of the plant refers to Texas mountains, which in Colorado would probably be called "flat ground." Sorry.
