More Information

Description
  • Handsome male evergreen holly with natural cylindrical shape
  • White flowers in spring
  • Does not set fruit but is required to pollinate female varieties so they get fruit
  • One Castle Wall will pollinate up to five Castle Keep and/or Castle Spire
  • Plant within 50’ of the female varieties to ensure pollination
Details Botanical name: Ilex x meserveae 'Heckenstar'
Patent: USPP 14,308
Common name: Blue holly
Zone: 5 - 7
Sun exposure: Sun (> 6 hours sun) to part sun (4-6 hours sun)
Height x width: 5-8' tall x 3-4' wide
Flower color: White
Foliage color: Green
Season of interest: Year-round
How To Grow Soil:  Moist but well-drained soils are best. Dry soil in fall and winter (before the ground freezes) will increase the chance of winter burn.
Light: Sun (> 6 hours sun) to part sun (4-6 hours sun)
Water: Average - do not overwater, as holly can readily suffer root rot.
Space:  min. 5' apart. Plant this male variety within 50' of the female plants.
Fertilizing:  If desired, fertilize in early spring, once the ground has thawed, with a granular rose fertilizer. A second application may be made in late spring/early summer as well.
Winterizing:  2-3" of shredded bark mulch is important to protect the shallow roots and minimize water loss. Do not allow plants to enter winter "thirsty" – dry soil during cold, windy weather is the main cause of leaf browning or even the plant dying.
Maintenance:  None required. Because it does not set fruit, can be trimmed after flowering if desired.

New Growth already

Planted in partial shade at the end of May and has already begun pushing new growth. Arrived healthy. Very happy with this plant!

All 13 holly bushes (Castle Spire and Castle Wall) are STRUGGLING to grow.

Planted our 10 females and 3 males on April 23rd and now (12 weeks later) they all look the same size as when planted. Missouri has had a lot of rain, and I read that it is easy to over water, so have kept close watch on soil moisture below mulch. Evergreen fertilizer spikes between each bush for nutrients. Definite lack of new leaf growth! All are caged to protect from nibbling squirrels. Would not recommend these for a privacy hedge as their current "under 8 inches" will take forever to grow into a hedge. Pictures show the mulched trench planting and delivery size on April 23rd. The pic with my hand show current size. All are green, but hoping the energy is going into root growth because it sure isn't in the leaves.
