Wonderful bluish green mound, covered with typical bright-yellow St John's wort flowers in late summer. Occasionally self-seeds, but the offspring doesn't have quite the same habit as the named variety. Our original plant passed away several years ago, I should really get a proper replacement.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. About my plant portraits

Visitors to this page have left the following comments| Jerry Moore | Apr 25, 2009 | Do you have to prune this bush back in the springtime?
You can, but it's not necessary - besides taking the inevitable dead pieces out once the live branches leaf out. |
| Bob M. | Jun 15, 2009 | I have a beautiful, 3 yr.old Sunburst. It gets morning sun and afternoon sun til about 1:00PM. The first year it blossomed sparingly. Last year not a single bud would flower. So far, this year, it has lots of buds but they just won't open. It's planted in good soil and gets the right amount of water. Any suggestions?
Lack of full sun is all I can come up with. Good luck getting it to its full glory! |
| John Bies | Jun 22, 2009 | I want to start my subburst by seed, but cannot find anyone that sells it -- the only sources I have been able to find sell the plant. Do you know of any place that sells these seeds?
If I remember correctly, our original plant, purchased as a large potted specimen, was more impressive in its habit than the seedlings that followed. Our original is now gone, so I have no direct comparison. However, if you want the real thing, you may need to purchase a plant rather than seed. |
| oddjob | Jul 05, 2009 | Sunburst is a clone. It's not available by seedling. Any seeds from it would still be Hypericum frondosum, but they would not be Hypericum frondosum "Sunburst".
Agreed. My seedlings aren't nearly as full in habit as the now-deceased mother plant. I'll have to re-purchase the real thing one of these days. |
| Vivian | Jul 18, 2009 | I love this shrub, but I don't where I to find it. Any suggestions?
When we bought this a long time ago, it came from a local nursery that carried Monrovia plants. Hypericum 'Sunburst' is still in Monrovia's catalog, so it may be worth finding a nursery that sells their stuff. |
| Tonya | Aug 18, 2009 | Is Golden St. John's Wart the same plant that is in herbal medicines to assist in treatment of Depression?
The medicinal qualities are primarily associated with Hypericum perforatum (common St. John's wort). I don't know if other species have similar physiological effects. |
| Alice | Oct 01, 2009 | I just bought a house which had this bush.. it was over 4' tall and 5' wide! In full bloom it was really pretty, but bees love it (they actually didn't bother me). There were also numerous seedlings growing around the garden, of which I've had to transplant to more roomy places.

| weezie | Nov 07, 2009 | I don't know much about plants, I just love them. I never knew the name of this plant until I found it on your website. I have a 3 yr. old bush in full sun and I love it because the deers don't love it. It looks like it needs a pruning. When can I do that? (zone 6). Thanks. |
| Mario Alberto | May 05, 2012 | I have this Shrub for a number of years and prune it in the winter to maintain its round shape at 3' diameter. It gets full sun and in summer it is covered in bright yellow flowers. Amazingly beautiful shrub. I have managed to grow seedlings from its seeds every year.

| Marshall Wilson | Nov 02, 2012 | Hypericum plants bloom on new growth. I have grown this plant and H. nudiflorum (a wild collection) and prune both back heavily in late winter. It is an easy way to clean the plant of old seed heads and improve the general appearance. Cutting it back also helps make the plants and flowers more dense in my opinion, but it is not necessary for the health of the plant or for new blooms. |
| Lois Hoffman | Jul 16, 2014 | I have had 4 hypericum frondosum for about 9 years, this last frigid winter really did a job on them. i cut one back almost to the ground, and no new growth came up. looks ugly and dead and the other 3 have bloomed very sparingly with little leaf growth. I love this plant because the bumble bees love it so much, can they be saved?
I've had these hypericums suffer sudden dieback too. Not sure what caused mine to decline, so I hesitate to suggest a remedy. Just take care of your surviving plants, and hope for a more vigorous season next year. |
| Wayne Dorsey | Dec 10, 2015 | When do you prune this plant? Late winter or after it blooms.
I remove excess growth in late winter. I don't know if that's the optimal schedule, it's just when I get around to it. I don't shear shrubs, so I always get flowers, even for plants that bloom on old wood. But I suspect that this one blooms on new wood, so it's safe to prune before new growth starts. |
