Planting & Care

Where to Plant

  • Sunlight: This hydrangea thrives with four to six hours of morning sun followed by dappled afternoon shade. While it can handle more sun in northern climates, excessive afternoon heat in the south will cause the large leaves to wilt and may bleach the flower color.
  • Soil: Aim for rich, well drained soil that stays consistently moist but never soggy. If you have heavy clay, mix in organic compost to improve drainage, or plant in a slight mound to keep the crown from sitting in standing water.

Watering Requirements

During the first two growing seasons, provide one inch of water per week to help the root system expand. Once mature, Froggie™ is moderately drought tolerant, but inconsistent moisture will lead to smaller flower heads and crispy leaf edges. You should deep soak the base of the plant twice a week during summer dry spells to maintain the vibrant bloom turgidity.

Pruning Tips

Since this variety blooms on old wood, meaning the flower buds are set during the previous summer, you must prune only immediately after the flowers fade in late summer. Avoid cutting stems back in the spring or winter because you will remove the upcoming season's flowers. Think of it like a scheduled maintenance visit: removing spent blooms and dead stems every year encourages the plant to direct its energy into healthy new growth.

Fertilizer Needs

Apply a balanced, slow release fertilizer early in the spring as soon as you see new green growth emerging. Avoid high nitrogen fertilizers late in the summer because this stimulates tender new foliage that can be easily damaged by the first frost. If you want to influence the bloom color, use aluminum sulfate for blue tones or garden lime for pinker hues, ensuring the soil pH remains stable.

The Froggie™ Bigleaf Hydrangea shrub (Hydrangea macrophylla 'COF HM2') is one of a kind! Plant yours today for a pop of color and texture. This unique Hydrangea is a new, dense mophead with colored sepals that start out green-purple and mature pink. Heat tolerant, Froggie™ is ideal for warmer climates! People will stop and stare at this beauty! Butterflies to come to check out these blossoms!

The sepals are extremely thick and persistent. This is a strong plant that will hold up for a long time! Strong stems hold up defiantly against storms and rain, plus this Hydrangea has gorgeous flowers that are used for cut flowers or landscape decoration. These are pH-dependent blooms, so pick up a soil tester to be sure what you will be planting Froggie in! Plant in more alkaline conditions and you'll enjoy slightly pinker blooms, while more acidic these might edge closer to a moody blue. Neutral pH soils keep these blossoms delightfully green and purple!

In the fall, you can expect the pretty pink to deepen into a rich, fall red. With foliage and dried blooms lasting on the shrub well into fall until frost, USDA growing zones 6 through 9 will be able to enjoy the uniquely hued mopheads and wonderful foliage of this Bigleaf Hydrangea!

Planting and Application:

Provide your Hydrangea Bush with a partly shaded location so the full brunt of the summer sun doesn't give them stress. They thrive in those afternoon shady spots, you know, those ones under a big shade tree or around a shaded porch? Brighten up those dull areas with this gorgeous plant for cooling hues and flouncy flowers that add interest to the shaded side of your foundation, walls and along the back of your property where we could all use some oomph.

This Hydrangea is most commonly used in low hedges, mixed-shrub borders, cutting gardens, or as a backdrop for your perennial garden. There are so many possibilities! Plant near water features or a shady gutter where they can soak up the moisture, or close - but not too close, to a shady pond, brook or stream.

  • Green Mopheads Accented in Pink, Purple or Blue
  • Big Coarse Toothy Green Foliage
  • Reddish Fall Color
  • Great in Containers, Low Privacy, Hedges & Cut Flowers
  • Great for Moist Shade
