As needed
  • water dropWater

    The Spider Flower should be watered regularly, aiming for once a week during active growth and less during winter, ensuring the soil is well-drained and never waterlogged. Deep watering is preferred to encourage strong root development—use about 1 gallon per watering for an established plant, adjusting based on rainfall and temperature.

  • sunLight

    Spider Flowers flourish in full sunlight but can tolerate partial shade. The best spot for this plant is in an area where it can receive at least 6 hours of direct sunlight daily, which encourages optimal growth and blooming.

  • thermometerTemperature

    Spider Flowers are hardy in warmer climates, with the ideal temperature range between 60°F and 75°F. They can survive minimum temperatures down to about 20°F but may suffer frost damage; temperatures above 90°F might stress the plant if not well-watered.

  • scissorsPruning

    Prune the Spider Flower to maintain shape and encourage bushier growth, typically after the blooming cycle in late winter or early spring. Cut back by about one-third, removing any dead or spindly branches, to promote healthy new growth.

  • circleLife cycle

    Grevillea 'Olympic Flame', also known as Spider Flower, begins its cycle when seeds are sown or cuttings are taken to start new plants. The seeds germinate, or the cuttings root, eventually developing into juvenile plants with characteristic needle-like leaves. As the Spider Flower matures, it enters a vigorous growth phase, producing robust woody stems and evergreen foliage, and becoming increasingly drought and frost tolerant. The adult plant reaches flowering maturity, where bright red, spider-like flowers blossom, primarily in winter and spring, attracting birds and insects for pollination. Following pollination, the plant develops fruit which are follicles that release seeds when mature, ready to start a new generation. Throughout its life, the Grevillea 'Olympic Flame' may undergo pruning to maintain shape and promote denser growth and flowering.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Grevillea 'Olympic Flame' is often propagated through semi-hardwood cuttings, a method most effective during the late summer to early fall when plant material has partially matured but is not fully hardened. To undertake this propagation, a grower should select healthy, semi-ripe stems and cut a section approximately 4 to 6 inches (10 to 15 centimeters) in length, just below a leaf node. Leaves on the lower half of the cutting should be removed, and the cut end may be dipped in rooting hormone to facilitate root development. The cutting should then be placed in a well-draining propagation mix, ensuring good contact between the mix and the cut end. Maintaining a humid environment by covering the cuttings with a plastic dome or bag and placing them in indirect sunlight can improve the chances of successful rooting, which should occur in several weeks. Once roots are established, the new plant can be gradually acclimatized to less humid conditions before transplanting into its permanent location.
