No matter which variety you plant, Diamond euphorbia will light up your landscape with its sparkling white blooms all season. The only decision you’ll have to make is choosing which one to plant where.

  • For a bright, saturated pop of white in smaller spaces or along the border’s edge, choose Diamond Snow.
  • For an airy look near the border’s edge, and for a plant that will mingle politely with its neighbors, choose Diamond Frost.
  • To create a 2-3’ tall hedge or fill an expanse space in a larger garden, choose the super-sized Diamond Snow.

  • Diamond euphorbia makes a beautiful, low maintenance accent plant in the landscape. Expect to replace it every year unless you garden in zones 10-11 where it is perennial.
  • Spacing will depend on which variety you are planting. Diamond Snow and Diamond Frost are similar in size with a recommended 12-18” spacing. Diamond Mountain will need more room at 24-36” spacing.
  • If you want the plants to grow together, shave a few inches off of our recommended spacing listed above and they will form a dense grouping with no bare spots showing in between.
  • Diamond euphorbia requires well-drained soil that won’t stay wet for long after a hard rain. You may need to amend your soil to improve drainage before planting.
  • Mix a bit of slow release plant food into the soil before you add the plants. Follow the package instructions to know how much to use. This will ensure a small amount of food is available to the plants’ roots over the season.
  • Water your newly planted Diamond euphorbia immediately to help the soil settle in around the plants’ roots.


Diamond euphorbia flourishes under pressure. Little supplemental water or food is needed for it to thrive all season long. These truly are low maintenance flowering plants.


  • Diamond euphorbia may appear delicate, but they have a rock-solid constitution. ​They won’t wilt in all-day sun and heat but are versatile enough to bloom with just a few hours of cool sunlight each day.
  • Though their flower power will be strongest in more sun, if a few puffs of white is all you’re looking to add to your shade garden beds, Diamond Frost will do the trick.


  • Plants growing in hanging baskets tend to dry out much faster than those planted in heavier upright containers and in the ground. This is especially true when they are hanging in windy areas or in full sun all day.
  • Diamond euphorbia prefers for its soil to dry a bit between each time you water.
  • To figure out if it is time to water, stick your finger down in the soil up to your first knuckle. If the soil sticks to your finger, it is moist enough to make it through the day without watering. If not, it’s time to water.
  • If you don’t have much time to water or if you tend to travel in the summertime, consider investing in a WaterWise® self-watering kit. It saves time and water, is simple to use, and waters up to ten containers at once from a single faucet.


  • Diamond euphorbia needs less plant food than hungry annuals like petunias, so it is ideal to pair them with plants like begonias, browallia, bidens and impatiens.
  • At time of planting, mix some Proven Winners continuous release plant food into the soil. Follow package directions for rates.
  • About once per month, feed them with Proven Winners water soluble plant food to provide a quick burst of nutrients to the plants.
  • If your plants start to get leggy partway through summer, decrease the rate of feeding.
  • Any brand of plant food meant for flowers will work for your hanging baskets. But we recommend Proven Winners water soluble and continuous release plant foods because they are specially formulated with micronutrients to help our varieties grow bigger, stronger, and bear more flowers.


  • Diamond euphorbia rarely, if ever, needs to be trimmed. This is one plant that won’t require any pruning or deadheading all season to keep its good looks and shape.
  • If you do want to trim these plants, keep in mind that euphorbias have a sticky white sap running through their stems that will seep out when you cut them. This sap can be a mild skin irritant, so it’s a good idea to wear gloves when you trim them.
