I grew up in NJ with spectacular red tulip magnolias. I am now in NH but would like a signature tree, single stem with late blooming red or yellow flowers that has interesting branch shape and is tolerant of zone 5. Is the Galaxia, Ann or black vulcan right? Can you send a catalog ? What is the availability right now? Guarentee? etc

Based on your zip code, your winter cold hardiness zone is 5A or the coldest part of zone 5. Depending on the microclimate where you garden, it might be as cold as zone 4. So I would suggest you look at the deciduous magnolias with the best cold tolerance. Magnolia x Randy as well as Ann are both considered hardy into zone 4 and have purple exteriors in their flower coloring; Elizabeth is a pale yellow hardy to zone 4. (Vulcan, Galaxy and Black Tulip are hardy into zone 5 as are most of the M. soulangiana cultivars.) Your local county extension and professional nursery staff should be able to help you evaluate the site and based on their local experience suggest whether you should probably be conservative or go ahead and try the zone 5 trees. They should offer a good selection of cultivars that do well in your local area and may have suggestions besides these.

Monrovia is a wholesale-only nursery and so there is no catalog beyond the on-line descriptions at the web site. You would need to check with your local retailers to determine pricing and availability. They are independent stores and each carries its own selection of plants. Also, any warranty is based on the retailer's individual policy. There is a zip code based dealer locator to help with contact information at

Enjoy your magnolia!
